Klaus We wouldn't want to keep people who are bringing the club into disrepute now, would we?
It's not about right or wrong here though, is it? It's about power. As the piece points out, Arsenal acted against Bonnick when he tweeted about Israeli genocide, not when he made a controversial public appearance per se.
That's because Bonnick's anti-Israeli comments led to a "piling-on", or realistically some Zionist group chat has made it its business to make sure Bonnick got cancelled, and no doubt contacted Arsenal privately up the food chain to ensure this.
It's what was happening to UK Labour organisers, parliamentarians and members during the trumped-up "antisemitism crisis". All very well noting the nuances of the "tropes" of anti-Zionist rhetoric while the next ten thousand civilians get massacred ...
Meanwhile the club will have been advised behind the scenes that Partey's case shouldn't warrant any sanction based on all the usual rationales.
